I am in the process of updating interior and exterior lights to LED. Thus far, results have been rewarding.
One Caveat however - any bulb that flashes - upsets the electronic control system, which seems to be surprisingly hysteria prone in an otherwise Rambo tough machine. There are solutions available, and a great amount of information on this site. I just need some research time to find the best answer.
The central brake light, which does not flash, is an ideal upgrade candidate, as are the interior lights.
